GEORGE J. FRIEND, 0E KINGSLEY, OREGON.

WEED- DESTROYER AND CULTIVATOR.

SPECIFICATION forming part of Letters Fatent NO. 652,513, dated June 26, 19 00.

Application filed February 8, 1900. $erial No. 4,527. (No model.)

v citizen of the United States, residing at Kings ley, in the county of W'asco and State of Oregon, have invented certain new and useful Improvements in Weed-Destroyers and Oul-.

tivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to agricultural machinery principally designed for preparing the soil to receive the seed. In its specific application the implement is intended chiefly as a summer fallow-weed destroyer.

The improvement consists of an implement which is adjustable and under the control of the driver and which can be regulated to run deep or shallow, as desired, and which may be thrown out of action without necessitating the stopping of the team or the dismounting of the driver.

For a full descriptionof the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and the drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure 1 is a top plan view of an implement specially designed for attaining the objects of the invention. Fig. 2 is a longitudinal section 011 the line X X of Fig. 1 looking in the direction of the arrow andshowing the adjusting instrumentalities. Fig. 3 is a section on the line Y Y of Fig. 1 looking in the direction of the arrow. Fig. 4 is a detail top plan view of a plow or cultivator shovel and its mountings. Fig. 5 is a perspective view of a hanger. Fig. 6 is a perspective view of a plow and colter. Fig. 7 is a perspective view of the parts shown in Fig. 6, the colter being detached. Fig. 8 is a side elevation of the plow and colter, the near share or wing being insection. i

Corresponding and like parts are referred to in the following description and in all the views of the drawings by the same reference characters. I

The frame is of oblong and rectangular shape and may be of any transverse extent corresponding with the tract to be covered by the implement in onetravel over the field. The frame consists of the frontbeam 1, rear beam 2, andend or. side beams 3, the several beams being rigidly attached atjtheir meeting ends. The pole or tongue 4 is centrally disposed with reference to the frame and is rigidly attached to the frontandrear beams land 2. The axle5 is of the crank type and is mounted in'bearings'applied to .the end beams 3, thejprojectingtcrminals of the axle receivingthe ground-wheel Gand the intermediate portion the cultivating or earthtreating devices.

The individual plows, cultivators, or earthtreating devices are of duplicate construction. Hence a detailed description of one only will be given. The beam comprises parallel members 7, having their forward ends divergent, as shown at 8, and pivotally connected to the front-beam 1 by means ofhook or eye bolts 9. In the preferable construction the beam is formed of a single bar, which is folded or doubled upon itself at its central point. The standard 10 has its upperfend fitted between the members 7 and secured thereto by means of a bolt 11 or analogous fastenings, the lower. end of the standard being forwardly curved and expanded, so as to provide a seat for the plow or cultivator-shovel 12, which is secured thereto. This plowor culti\-'ator-shovel 12 is of the double-winged type and is secured at a central point to the standard 10, the point having a notch or open-ended slot 13 to receive the lower end of the colterle. A brace 15 connects the standard 10 with the beam, the upper end of the base being secured between the members 7 in a similar manner to the standard 10.

The colter 14 is disposed in advance of the standard 10 and directly abovethe foot and curves upwardly and rearwardly from its lower front end and is attached to a side of thestandard, the upper attachingjend being offset, as shown at 16, andsecured tojthe standard by the same boltor fastening 17 employed for attaching the lower end of the brace 15 thereto. The lower forward end of the colter projects below the plane of the plow or cultivator shovel 12 and has an extension 18 to underlap the shovel and the front end of the expanded end of the standard 10. The lower edge of the colter is made rounding to ride over the ground more easily, and the portion directly above the point of the plow 12 is formed into a hump 19, which performs the greater part of the work.

The plow-beams, as previously stated, have loose or pivotal connection with the front beam 1 of the frame, and they likewise have loose connection with the intermediate portion of the axle 5 at a point in the rear of its axial line. The connection between the plowbeams and the axle 5 is effected. by means of hangers 20, which are in the form of yokes or staples having the lower ends of their side members bent in opposite directions, as indicated at 21. The hangers 2O straddle the axle 5 and pass between the members 7 of the plowbeams, and their bent ends 21 engage with the-said members 7 and hold the plow-beams and axle in the desired position. Inasmuch as the center of movement of the axle 5 is intermediate of the front and rear supports of the plow-beams it is necessary that the .connection between the rear ends of said plowbeams and the axle be movable in order to allow for the turning of the axle 5 when raising and lowering the plows or cultivatorshovels. The plows or cultivators have a staggered arrangement in order to admit of the wings of adjacent plows overlapping, whereby spaces or untouched portions of the soil between the rows formed by adjacent plows are wholly obviated. Certain of the plows are arranged in advance of the intermediate portion of the axle 5 and other plows are disposed in the rear of said axle. The intermediate plows are connected with their.

beams in advance of the axle, whereas the alternate plows have attachment with their beams at a point in the rear of said axle. This disposition of the plows results in the staggored arrangement referred to and enables the attainment of the end stated.

The turning of the axle causes the intermediate portion to rise and fall with reference to the plane of the frame and effects a corresponding movement of the plows or cultivators to cause them to run deep or shallow, as required. The following means are provided for moving the axle, and consist of a plate 22, secured to a side of the pole or tongue 4 and having a pendent portion 23,

to which a bar 24: is pivotally connected, said bar extending rearwardly and terminating in a hook 25, which embraces the middle portion of the axle. An elbow-shaped lever 26 is fulcrumed to the pole 4, and the rear end of its horizontal arm is connected by links 27 with the pivoted bar 24, and said lever has the ordinary hand-latch 28 applied thereto and adapted for cooperation with a notched segment 29, secured to the pole 4 for holding the parts in an adjusted position.

\Vhenthe implement is drawn over the field for destroying weeds or for cultivating purposes, the lever 26 can be moved to raise or lower the plows to cause them to enter the soil to the requisite depth or to throw them entirely out of action.

Theterm earth-treating devices includes the plows or cultivator-shovels 12 and their supporting means, as the standards 10, and in the claims when the term earth-treating devices is employed in connection with the beams it is to be construed as referring to and including the cultivator-shovels and standards.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. In combination, agang of earth-treating devices pivotally supported at one end, an axle having crank portions mounted in bearin gs located intermediate-of the main portion of the axle and the pivotal supports of the said earth-treating devices, sliding connections between the intermediate or main portion of the axle and the swing ends of the earth-treating devices, and means for turn ing the axle to efiect the raising or lowering of the earth-treating devices and hold them in an adjusted position, substantially as set forth.

2. In combination, a frame, beams bearing earth-treating devices and having pivotal con 1 nection at their front ends with thesai-d frame, a' crank-axle having its crank portion mount- 1 ed in bearings applied to the frame, hangers applied to the intermediate portion of the axle and having slidable connection with the a rear ends of the aforesaid beams, and means for turning the axle to effect a raising and lowering of the earth-treating devices, substantially as set forth.

In combination, a frame, a series of beams having pivotal connection at their foot ends with the frame, a crank-axle having its crank portions mounted in bearings of the frame, loose connections between the intermediate portion of the axle and the rear ends of the aforesaid beams, means for raising and lowering the rear ends of the beams, and earthtreating devices secured to said beams, the .intermediate earth-treating devices having attachment with the beamsin advance of the axle and the alternate earth-treating devices having connection with their beams in the rear of said axle, substantially as set forth.

4. In combination, a plow or cultivatorshovel secured to the standard and having a notch or open slot at its point, and a colter secured at its open end to the standard and having its lower end fitted into the said notch or slot of the shovel and having a rear extension underlapping the plow-point and lower portion of the standard, substantially as described.

5. In combination, a pivotally-supported plowbeam comprising parallel or spaced members, a crank-axle, means for turning-the crank-axle in its bearings and holding it in an adjusted position, and a hanger of approximately U form mounted upon the axle and passing between the members of the plowbeam and having the terminal portions of its side members bent in opposite directions to engage with the members of the plow-beam substantially as set forth.

6. In combination, a frame, a series of beams comprising parallel members having their forward ends divergent and pivotally connected to the front beam of the frame, plow-standards arranged alternately in front of and in the rear of said axle and connected with the respective beams, hangers applied to the axle and having slidable connection with the rear ends of the pivoted beams, an operating-lever, and a hooked bar having connection with said lever and with the intermediate portion of the axle, substantially as specified.
